A productive crop depends on a complex, interconnected system of soil minerals, nutrients, microorganisms and plant roots. Phosphorus sits at the center of many processes that drive crop growth, from early root development and establishment to energy transfer, reproductive development and seed production.

Having phosphorus in the soil doesn’t necessarily mean having phosphorus available to the crop when it needs it most. When phosphorus availability falls short, crops can experience restricted root growth, delayed maturity and ultimately reduced yield potential. The challenge then isn’t simply supplying enough phosphorus. It’s making sure it’s in forms that the crop can access and use.

Phosphorus availability is a moving target

Think of the phosphorus in the soil as a reserve. It enters the soil through fertilizer, manure, crop residue and other organic matter. Soil phosphorus exists in two main forms: organic and inorganic. Some of it is readily available for plant uptake. The rest is held in forms that plants can’t immediately access – including phosphorus bound to soil minerals and phosphorus tied up in organic compounds.

That's why a soil test can show a significant amount of phosphorus and still have a crop that struggles to access enough of the nutrient during critical stages of development. Soil phosphorus is constantly moving between different forms, and factors such as pH, clay content, moisture, temperature and biological activity influence how much is available at any given time.

Inorganic phosphorus, including orthophosphate, is the primary form taken up by plant roots. But once phosphorus enters the soil, it can interact with minerals such as calcium, iron and aluminum, forming compounds that are less available for plant uptake. The specific reactions depend on soil conditions, including pH.

The other portion of the soil's phosphorus, organic phosphorus, is held within organic compounds. This source of phosphorus must first be released through a process called mineralization before it can become available to plants. A system beneath the plant’s roots drives this cycle of phosphorus availability.

Enzymes: the key behind nutrient cycling

Nature has its own system for unlocking nutrients. Microbes and plant roots contribute to nutrient cycling by producing enzymes that help drive the biochemical reactions that transform nutrients from one form to another. The role of enzymes is to help speed up the process of decomposing organic matter and to release plant-available nutrients.

Think of enzymes as keys. When they encounter the right compound, they help unlock nutrients in compounds that plants cannot use directly by breaking that compound down into a different form. When more enzymes are active in the soil, more nutrients are made available where the plant needs them.

Microbes and enzymes are not interchangeable. Microbes are living organisms; enzymes are the tools they produce. Unlike enzyme solutions, the microbial activity of biological products can vary with environmental conditions such as soil temperature, moisture, pH, and nutrient availability, which can lead to inconsistent nutrient-availability benefits in some cases. Enzymes don’t need to survive or propagate in the soil, they can go right to work once applied.

An enzyme-based approach can directly target a specific nutrient-cycling process. Rather than relying on an organism to establish and build over time, the enzyme can be delivered directly to the soil. This helps shorten the biological pathway between the technology and the biochemical reaction it is designed to support.

With more phosphorus-use-efficiency products available to growers, choosing the right product means looking beyond the label. Not all technologies take the same approach to improving phosphorus availability, and understanding how a product works can be an important part of evaluating what it can deliver in the field.

By delivering enzymes directly to the soil, plants get the nutrients they need when they need them. While microbes are an important part of the soil phosphorus cycle, enzymes are key for driving the reactions that transform nutrients like phosphorus. Without enzymes, yield potential is left on the table and opportunities to improve nutrient-use efficiency, crop productivity and return on investment are missed.

A direct approach to unlocking organic phosphorus potential

A significant portion of soil phosphorus can be held in organic compounds. Through mineralization, enzymes help break the bonds within those compounds, releasing phosphorus into forms plants can take up.

PHOSFORCE^™ nutrient enhancer supports this process with active ingredient, phosphodiesterase, an enzyme that helps break the bonds holding phosphorus within organic compounds. PHOSFORCE delivers the enzyme directly to the soil rather than relying on microbes to produce it, accelerating the chain reactions that transform locked-up organic phosphorus to plant-available phosphate. That gives growers a consistent, targeted way to support phosphorus mineralization and help make more phosphorus already in the soil available to the crop.

Continued access to phosphorus is important to helping crops reach their yield potential. In corn and soybeans, adequate phosphorus availability supports early root development and establishment while contributing to energy transfer, reproductive development and seed production as the crop progresses, which ultimately impacts yield.

One application of PHOSFORCE provides up to eight weeks of phosphorus mineralization, helping support a crop’s nutritional requirements. More than a decade of trial data across 15 crops and multiple application methods shows PHOSFORCE is a proven solution for enhancing soil fertility and crop productivity.

For growers, that creates an effective, immediate way to unlock untapped organic phosphorus reserves in the soil to improve plant vigor, support root development and optimize yield potential. Take advantage of an existing nutrient resource to enhance phosphorus use efficiency and return on investment.
